I checked on eBay and I can in fact get the Pentax Optio S digital camera for $350. And I think I might be able to get at least $300 for my current camera, if not a few dollars more. Which means I can get the $400 (normal retail price) camera of my dreams for the difference of about $50.
The catch: the camera of my dreams requires a USB port to download pictures. My USB port does not work.
